Functional failure or malfunctions due to faulty pilot air supply
• Supply every pressure zone with working pressure and pilot pressure. Do not form pressure-free
zones
4.2.1.4 Forming pressure zones.
• Use only one supply component for the pilot air supply in every pressure zone.
• Required pilot pressure at port (12/14)
